摘要
为确保某块石土层基坑的顺利开挖,结合工程实际,对工程概况、工程地质与水文地质条件及方案选择等主要问题作了分析,提出以H型钢、压密注浆、高压旋喷的SMW工法作为防水、挡土体系,结合砼支撑及锚杆的结构形式,取得了较好的预期效果,充分地体现了安全、经济、合理的特点。
In order to excavate the rubble stone soil layer foundation pit successfully, the authors analyzed the project situation, the engineering geology and the hydrogeologieal conditions according to the actual characteristics of the project ,then ,the scheme of SMW by H section steel union the compaction grouting and high pressure jet grouting to stop seepage and support soil are put forward, and the expected result has been reached, and the advantage of safety, economical, rational characteristics are reflected sufficiently.
